Unforced variations: Jan 2016

Filed under: — group @ 1 January 2016

Happy New Year, and happy new open thread.

As per usual, nuclear energy is off-topic – it’s not that it’s uninteresting, but it ends up dominating conversation to the total exclusion of everything else and just becomes repetitive and dull. Recent excursions on this topic shows what happens when we relax the moderation, so back to being strict about this. If you want to discuss this, please go somewhere else.

Unforced Variations: Dec 2015

Filed under: — group @ 13 December 2015

This is a belated open thread for this month, for anything non-COP21 and non-AGU related.

#AGU15

Filed under: — gavin @ 13 December 2015

So this week it’s the biggest Earth Science meeting on the planet



There is a lot of great science that will be freely streamed via AGU On-Demand (registration required), and there’ll be a lot of commentary using the hashtag #AGU15. Many posters will be available online too. A few highlights have already been discussed by Victor Venema related to the surface temperature station datasets, but there’ll be much more on offer if you dig deeper.

As the week goes on, we’ll link to anything good we see, and we’ll be happy to host any commentaries that anyone has on specific climate sessions or talks.

Happy conferencing!

#COP21

Apparently there is a climate conference of some sort going on. Happy to answer any science questions as they arise…

Hiatus or Bye-atus?

Guest commentary by Stephan Lewandowsky, James Risbey and Naomi Oreskes

The idea that global warming has “stopped” has long been a contrarian talking point. This framing has found entry into the scientific literature and there are now numerous articles that address a presumed recent “pause” or “hiatus” in global warming. Moreover, the “hiatus” also featured as an accepted fact in the latest IPCC report (AR5). Notwithstanding its widespread use in public and apparent acceptance in the scientific community, there are reasons to be skeptical of the existence of a “hiatus” or “pause” in global warming [Ed: see also this previous post]. We have examined this issue in a series of three recent papers, which have converged on the conclusion that there is not now, and there never has been, a hiatus or pause in global warming.
